2 things I would like to see changed. The original custom color selector was better than the these presets that are available now. The other is the sizes of the font jump by twos, an input to put in a custom font size would be great

PDFiller Review Great experience, filling out the documents just takes a bit of time. Gives my documents the professional look vs handwritten documents Seems like there is 1 too many steps to saving a document and then viewing and saving to my desktop.

What do you like best? That it looks professional, it is easy to use, and there are so many common templates to use which are always necessary, especially for a small business owner. What do you dislike? That it is always such a process to sign in if I am not at my home computer. What problems is the product solving and how is that benefiting you? It allows me to complete my forms needed in a timely manner and saving time for me is ALWAYS beneficial. I am more productive. Title for your review: Excellent site for completing and sending important professional looking documents.

My Issue Only real issue I have is there doesn't seem to be any way to save the same PDF after I've modified it with the sight. If there was a way to do that I'd have probably given 5 star
